What LCP is made of
A flat LCP number tells you something regressed. The subparts tell you whether it was the server, resource discovery, the download, or rendering.

Main thread work
Axe violations axe-core 4.13.0, full rule set
6 violating nodes across 3 rules, 285 passing. This is a standalone axe run, stricter than the subset Lighthouse folds into its score above — and it is the second tiebreaker in the ranking.
-
serious
list— <ul> and <ol> must only directly contain <li>, <script> or <template> elements 3 nodes -
serious
color-contrast— Elements must meet minimum color contrast ratio thresholds 2 nodes -
moderate
page-has-heading-one— Page should contain a level-one heading 1 node
Accessibility failures 2 of 24 audits
Tracked as a count, not just the score — the weighted score is coarse enough that you can ship a broken component and barely move it.
-
list— Lists do not contain only `<li>` elements and script supporting elements (`<script>` and `<template>`). 3 nodes -
color-contrast— Background and foreground colors do not have a sufficient contrast ratio. 2 nodes
Hygiene
Changes rarely — which is exactly why a change is worth noticing.
